covering indoor cistern

I found an indoor cistern in my house yesterday. They covered it with cardboard (?) and then vinyl flooring, and then carpet on top of that. Around it looks like plywood, which is rotted and doesn't hold weight. It was pretty uneven, but in a corner. So I am not going to fill it in, but the floor is falling in around it. What can I put down to waterproof the floor around it and seal it off? Or should I leave it unsealed if I want to use it? But still I have to figure out what to put on the floor.

Welcome to the forums! I was hoping someone with an interior cistern would chime in, but guess not. Anything you put over the water/moisture containing vessel that will rot is not advisable. Do you want to permanently seal it, or is leaving it accessible required? You say "cistern", and was wondering if it is in your basement and is a sump pump?
